This invention relates to a new type 3f shipping case of fibre 'or corrugated card or equivalent material.

. It is the ob'ect of the present invention to 5 afford a fine end case of; the collapsible tube type which employs an absolute minimum of material and in which the body blank can be stitched by the manufacturer,

Referring to the drawin s: Fig. 1 is a perspective one form of the case.

The body sheet as shown in Fig. 5' is the 85 same as ordinarily employed in the prevailing type of container the slotted end container. It comprises four side walls, a, 12,0 and d, together: with the manufacturers seam flap e. This can be stitched, as shown the manufacturer to provide a collapsible tube. This is the custom with the slotted end container. However, with the slotted and container. the four flaps on each end of the tube are relatively lar e and the outer set are intended to be over apped over the inner set, and each set must be of the same width, for otherwise an variation would result waste in the. blan The result is that considerabl more material is used in this slotted en container than is necessary to make the several walls of this six-sided receptacle. It is the object of the present invention to overcome this large waste and yet afl'ord a container, namely,'a collapsible tube 'n which the manufacturers of another form of 'only in the same to properly seal a'case of will ordinarily have seam can be made by the paper board man This container is an end loader sense that the slotted end container is an end loader. If the container has a tube of greater length than its cross section, the box may be said to be an end loader, but obviously the tube may be of greater cross section than its height, in which ufacturer.

case, it would be more correct to call it the side loader.

- In place of the large flaps in the slotted container each of the walls of the tube is provide with a short corner flap, a, a 1), b 0 0 ,11 and d These flaps a, 6 c and d can be'easily stitchedto a plain bottom wall f, such as shown in this involves no problem of handling the anvil. g

However, thedifliculty lies in being able the kind shown in This is accomplished by Figs. 1, 3 and 5.

more clearly portrayed in the arrangements, Figs 3 and 4. For instance, positions of the blade anvil are shown lzy the roman numerals I, II, III and I The top wall 9 iece of material and is shown in Fig. The first thing to do is to stitch 'thls to the collapsible tube. In fact, this first stitching operation might be easily per-.

formed by the manufacturer and the case shipped with the cover 9 stitched in place. This may be stitched to any one of the flaps a 6, oand (P. It happens in the drawings to be shown as-stitched to b. This flap b to be turned under the cover 9, and stitches leavin a space between some of the stitches, here s own at the middle, for the insertion of a blade anvil; the stitches 1, 2, 3- and 4 1, 2, 3 and 4 are taken Fig. 7, as p here the four 1s a plain, rectangular are shown taken by a blade anvil, but obviously they might be made by any other anvil. a

After this first narrow flap has been stitched to the cover, the container may be charged or for that matter might be charged be before the stitching of the cover stitchin of the c and 1 becomes the sealing operation. Th is effected by placing the blade anvils in un-' der the cover and the-two side narrow flaps 0 and a as shown in positions II and III.

over tothe other flaps a), '1'

These flaps c and a are preferably stitched on the out'slde of the cover but mi ht be on the inside. Then the anvil is shi ted to IV, and stitches 15 to 19 taken for tying the narrow flap d to the cover 9. This corner flap d is preferably put on the outside but might be on the inside.

It is preferable to have all the corner flaps, if possible, on the outside of the cover flaps for practical experience has shown that -a fibre container in'which the wall abuts into the inside corner of the flaps is much stronger and more durable than one where the creases in the flaps do not enclose the edges of the wall. It is therefore to accomplish this purpose that I have designed the modified structure shown in Figs. 2, 4, and 6 of the drawings, and some of the other seetional views.

The structure here is precisely the same except one of the flaps, which happens to be here shown as b, is slotted near one end as at h. This permits the larger portion of this corner flap to be turned out on the outside in place of on the inside as is the case for the first stitched flap in the other form. This makes a stronger case by reason of all the edges of the end walls resting in all the creases except for a small distance at one corner. The short flap, as is seen in Figs. 2 and a, is turned in. This permits the anvil to be inserted for the final stitching-operation, through the opening permittedbythis turned in flap. section. This box can be stitched in precisely the same way as the stitching shown in Fig. 3, but I prefer to show here the stitching running continuously around as this permits more ease in manipulating the anvil in the final stitching operation, permitted by the small turned-in flap section.

I am aware that the three-blank flush-end shipping case per se is not new; it is shown in a lar e number of my prior patents and in some 0% the other prior patents, but-these flush-end cases heretofore designed are all side loaders as opposed to what may be conveniently called an end loader. That is, the body blank itself was not used as a body tube but the body blank affords the cover flaps which cover up the opening through which the case is charged. This has been a necessary detail of the three-blank flush-end case heretofore designed. In the present case the body blank must be stitched into a tube before the case is packed. In the reviously existing flush-end cases the body lank can gnly be stitched into a tube as part of the final sealing operation. This is an essential difference not only in structure but in handling these boxes.

My container is built entirely of fibre board, corrugated board, straw board, or equivalent material, and requires no frames of wood or other material to obstruct the corners of the case either outside or in.

What I claim is:

1. A new container, comprising a body blank of four walls united together in a collapsible tube, a closure for the bottom of the tube, the walls at the top of the tube being provided with narrow sealing flaps, and a separate top panel sewed to the turned in sealing flaps by stitching some of the flaps to the panel and leaving an unstitchedportion through which a blade anvil is inserted to complete the sealing by stitching'of the remaining flap or flaps.

2. A new container, comprising a body blank of four walls provided with a manufacturers seam on one end stitched to the opposite end of the blank to form the same into a collapsible tube, a closure for the bottom of the tube, the walls of the body blank being provided with sealing flaps, and a separate top panel first stitched to one sealing flap and then stitched to the remaining sealing flaps by an anvil which in completing the stitching operation passes between one of the previously stitched flaps and a portion of the top panel.

3. The method of setting up and sealing a container, formed by a creased body blank forming four walls and four sealing. flaps, and a separate top panel, which method comprises forming the body blank into a tube, applying a closure to the bottom, stitching the top panel to one flap, then stitching the other two flaps, and in one of these operations leaving a space for the subsequent insertion of a blade anvil, and finally comletiiig the stitching of the remaining flap I y inserting the anvil through said un- 1 stitched portion.

4. The method of making and sealing a container, which comprises creasing and cuttin a blank to form four ali ned side walls an a manufacturers seam ap at one end and four fiaps at each side of the blank, the ones at one side being narrow, the fastening of the manufacturers seam flap to the opposite end of the case to make a collapsible tube, the ap lying and fastening a closure to one end 0 the tube, and sealing the case by turning in the narrow flaps at the opposite end of th tube in connection with the application of a separate top panel and the stitching said narrow flaps to the top panel and concluding the final stitching by a blade anvil slipped in between parts of the top closure along a side of the top panel which has already been stitched.

In testimony whereof I have afiixed my
